Math & Numbers
Compute engineering tensile strength σ_uts = F_max/A₀, yield strength σ_y = F_y/A₀ (optional), and the yield ratio σ_y/σ_uts from a uniaxial tension test. Forces in kN, area in mm² → stress in MPa. A₀ is the original cross-section. Yield ratio <0.55 high ductility, 0.55–0.85 moderate, >0.85 low ductility.

POST https://api.elysiatools.com/en/api/tools/tensile-strength-calculator| Name | Type | Required | Description |
|---|---|---|---|
| area | number | Yes | Original (unstressed) cross-section area of the gauge section, in mm². Engineering convention uses A₀, not the necked area. |
| maxForce | number | Yes | Maximum force reached during the test (at onset of necking), in kN. |
| yieldForce | number | No | Force at the yield point, in kN. Optional — when omitted, only σ_uts is reported (yield ratio needs F_y). |
| decimalPlaces | number | No | — |
